There's a patch series for this and pointer barriers (which Unity might want to use, too, for the BDB + multihead) on the xorg-devel mailing list. The crtc-clamping works and if we really wanted it the patch is relatively safe and could be FFe'd. The pointer-barriers need protocol changes, and I'd be hesitant to include them before the protocol has been finalised.
